As Oracle acquires Sun Microsystems, IBM is adopting technology from a small database company, EntepriseDB, that will make it easier for DB2 users to migrate away from the Oracle database system.
The move is unusual in that database companies typically offer some sort of migration assists, to lure customers off of rival systems. But IBM turned to a company based on the open source database PostgreSQL and implemented its ability to work with Oracle's PL/SQL stored procedures, Oracle data types, and Oracle database calls into its Postgres Plus Advanced Server.
EnterpriseDB spokesmen have claimed that an Oracle application can run unchanged with its Postgres Plus. Now Oracle applications will work "as is" with DB2 Release 9.7 as well, said Arvind Krishna, IBM's VP of database servers.
